The downhole inflow control device (ICD) could control the production profile of every section in horizontal well and the edge and bottom water coning, so it is important in enhancing oil and gas recovery. To quantitatively depict ICD's suitability in horizontal wells requires analyzing reservoir parameters like permeability variation coefficient, average permeability, the ratio of vertical permeability to horizontal permeability and the technology parameters like tube string size, horizontal section length, segment number and the pressure loss ratio between ICD and reservoir. With fuzzy mathematical method, this work has analyzed these factors through relative subordinate function and established the fuzzy comprehensive evaluation model to study the suitability of ICD in sandstone reservoirs by the weight of each factor and fuzzy relationship matrix. The fuzzy evaluation and simulation results prove this method could well evaluate the suitability of ICD in sandstone reservoirs and it is significant for the application of ICD in horizontal well development.
